Bohemian Grove Questions?

I have read some information and watched videos about Bohemian grove...I was wondering if all this Really was true..or just a bunch of quackery? I have also watched a video by a rap star named Immortal Technique called dancing with the devil, which also had some reference to Bohemian Grove..Is all this a bunch of lies..or is there some shady stuff done by our government..Also do you believe our government has done shady/underhanded stuff in the past..To get best answer please answer all ?'s intelligently
